SPECIFICATION forming part of Lettersratent No. 542,336, dated July 9, 1895.

Application tiled October l0, 1.894- Serial No. 525,535. (No model.)

nois, have invented a certain new and useful Pneumatic-Tire Fastener, of which the following is a specification.

My invention relates more particularly to pneumatic tires as used on bicycles, but it is not limited to that use. V

It also relates more particularly to pneumatic tires which are composed of two partsthat is, an outer casing or covering and an inner tube or air-tube. The description in the specification will relate more particularly to these two classes.

The objects of my invention are to have a means of attaching the pneumatic tire to the rim of a wheel without cementing it on, and which will also prevent the tire from creeping or moving on said rim; also to provide a means for closing the slit in the outer casing of said tire other than by lacing each time it hasbeen opened, as is now done; also to provide a means of attaining'these objects, which may be applied to the now-existing Atires or the tires now in use, with butlittle or no alteration to said tires. Iaccomplish these' cbt] ects by the means illustrated in the accompanying drawings, in which- Figure l is a longitudinal vertical section of a portion of a pneumatic tire 4and a portion of the rim of a bicycle-wheel, showing I my fastener in elevation and its preferable relation to the outer casing and inner tube of said pneumatic tire. Fig. 2 is a plan of my fastener, showing the slit in the outer casing in dotted lines. Fig. 3 shows a plan of my fastener in modified form, using wires to bind the tire onto the rim of the wheel. This View Shows the fastener in an opened position. Fig. 4 is a section of Fig. 3, showing the relation of the fastener and wires to the outer casing 4and inner tube of the pneumatic tire. Fig. 5 is a detail view of the fastening-stud of the fastener, which stud secures the fastener to the rim of the wheel. Fig. 6 is a plan of my fastener, showing a means of application when it is inclosed inthe outer casing. Fig. 7 is a plan view, as Fig. 6, with the fastener opened to the position requiredto remove the inner tube. Fig. 8 is a central longitudinal section through the fastener,'as shownin Fig. 6.

drawings.

Fig. lO is a section on the line y y of Fig. 6. .Figli is a detail view'of the lockingdink which fastens the two series lof the fastener together. f -Similar letters refer to like parts in the va` rions views ofthe drawings.

My invention is composed of two series or sets of thin narrow metal plates jointed or pivotcd'at required intervals and the series hinged or pivoted at one end and preferably having the stud forming the hinge or pivotpass through and fasten to the rim of the wheel by a nut. I have provided a hookinglink, So called, which I use in locking the two series of the fastener together when it isclosed or in position of use, thus preventing anyliability of its springing open. y

vIn the drawings, A represents the outer casing of the pneumatic tire and has init the or.- dinary slit for removing the inner or air tube.

B represents the inner or air tube, and is made in the ordinary form.

C is the rim of a bicycle-wheel, to which A the pneumatic tire is fastened.

D D E E are the four pieces of metal forming the two series or parts of my fastener. These are preferably made ot' thin narrow plates, but any other substance found desirable Inay be used, the object being to have each part stiff, yet light.v The parts D and E arel pivoted together by the `stud G, which stud, having on its lower end a screw-thread, is passed through a hole in the rim of the wheel and the nut G screwed on it till said stud is' firmly attached to said rim. This attachment is shown in detail in Fig. 5 of the To the parts D and E are attached the parts or plates D and E by means of the rivets or studs B2 and E2, the ends of which rivets or studs are extended, to allow. the fastening to them of the hooking-link M and also of the outer casing. lThe outer ends of the parts D and E are provided with studs or pins D3 and E3, to which the hooking-linkfN is fastened. The two pieces D and D on one side and E and E on the other form the two so-called series It is'not my desire to limit myself to simply two pieces on each side, but any convenient number may be used,the number shown being ample to illustrate my invention and for all practical purposes.

, This fastener is laced, preferably, to the inside of the outer casing, one series on each side of the slit in said casing, by the lacingstrings Il, which pass through said outer casing and said plates, thus attaching the fastener to the inside of the outer casing. Rivets may be used, if found convenient, and are illustrated and preferable where the fastener is inclosed in the edge of the outer casing, but lacing is preferred for tires now in use.

M and N represent the hookingdinks for fastening the two series of my fastener together. These are made of a thin piece of metal and have at one end a slot with an enlarged portion, as illustrated in the drawings by m and n. These locking-hooks are attached to the pivots or studs D2 E3, and the slots m and n hook over the studs E2 and D3 of the opposite series, respectively.

I have illustrated the locking-hooks as alternated, but they may be placed all on one side and hook on the studs on the opposite side as well, as I do not limit myself to any particular location of hooks.

In operating this device in connection with a pneumatic tire the fastener is laced to the inside of the outer casing of the tire, one series on each side of the slit in said casing. The fastener is spread and the inner tube in serted, when the fastener is closed and hooked.

The casing is then placed on the rim of the wheel, so that the pivot-stud G may pass through the hole in said rim, when the nut G is screwed onto said stud until it presses against the rim of the wheel, thus fastening 1 said stud securely to said rim, and in so doing attaching the fastener, which in turn will y hold the tire firmly in place on the rim of the wheel and prevent a creeping movement on said rim. air tube from the outer casing for repair, or

whatever else, the nut is removed from the stud and said stud loosened from the rim of the wheel, when the outer casing may be removed from said rim, the locking-hooks unfastened, and by spreading the fastener the inner tube exposed, and may be readily removed.

In the modification illustrated by the views, Figs. 3 and 4, the fastening-stud is omitted and in its place the wires F are used. These wires are attached to the fastener, as illustrated, one set of ends being attached near the pivot end and the other set at the opposite end of the fastener. The wires pass entirely around the tire between the inner tube and the outer casing. To attach the tire on the rim the fastener is closed together from the position illustrated in Fig. 3, and in so doing the wires will be tightened and bind said tire to the rim. The fastener when closed is hooked, as before described.

In attaching the fastener to the outer casing, as illustrated in Figs. 6, 7, 8, 9, and l0, said fastener is placed in the edge of the outer casing on each side of the slit and riveted, though the rivets may be dispened with, if desired. Its position and relation are clearly illustrated by the drawings. The lock- In order to remove the inner or ing-hooks may be used in this as in the other forms.

I do not wish to limit myself to any particular form of lockinghooks; but my object is to provide a hooking attachment fastening to the pivots or studs, which may be readily fastened and unfastened and which will hold the two series securely together when so fastened.

Having thus described my invention,what I desire to claim and to secure by Letters Patent is- 1. A pneumatic tire fastener, composed of two series of pivotally connected narrow plates so arranged that the series are pivotally connected at one end and that each member of one series is opposite its corresponding memberof the other series, in combination with locking hooks fastened to one series and hooking over pins or 'studs in the opposite series in such a manner that the two series are held firmly together when so attached all as set forth and described.

2. A pneumatic tire fastener, composed of two series of pivotally connected narrow plates, attached to the outer casing-of said tire at the slit in said casing and so arranged that the two series are pivotally connected with each other at one end by a stud which passes through and is attached to the rim ot' the wheel, all substantially as and for the use set forth.
